NCG seminar on the occasion of the 25th year jubilee of Mathias J.P.M. Lemmens at TU Delft

Peter J.M. van Oosterom (Editor)

This publication is a very special one for several reasons. First of all it is on the happy occasion of the 25th jubilee of Tjeu Lemmens at the TU Delft, which makes it a very pleasant setting. Second, this publication is the first publication of...

Proceedings of the Workshop on Assessment and Socio-economic Aspects of Spatial Data Infrastructures

Bastiaan van Loenen (Editor)

Socio-economic aspects of geographic information (infrastructures) (GII) are increasingly considered in GII development and especially in GII research. Where once the technological dimension of GII was the dimension assessed to be most relevant, it is now commonly understood that also the non-technical aspects should be addressed and understood in...

Michel Grothe and Jan Kooijmans (Editors)

In the geo-information community in the Netherlands the concept of Spatial Data Infrastructures has gained increasing attention. In the last two years this has led to several implementations especially in geoportals, operational web mapping services for...

Peter J.M. van Oosterom (Editor)

This publication is the result of the seminar ‘Standards in action’ on 17 November 2004 jointly organized by ‘Geo-Informatie Nederland’ (GIN, section Geo-ICT) and Netherlands Geodetic Commission, sub commission Geo-Information Models (NCG-GIM). The seminar is organized in...

N. van der Schraaf (Editor)

Last year the Netherlands Geodetic Commission decided to mark its hundredth anniversary, 20th February, 1979, with some kind of celebration. In the hundred years of its existence the Commission has not sought much publicity for its work. It is true that the publications and annual reports of..,

N.D. Haasbroek

The motive for Stamkart's triangulation carried out in the Netherlands, between 1866 and 1881, is already mentioned in the first section of Haasbroek's publication on the accuracy of Krayenhoffls triangulation and in the very detailed paper by...

The Working Group for Satellite Geodesy is part of the Sub-Department of Geodesy of the Delft University of Technology (THD) and is represented in the Netherlands Committee for Geophysics and Space Research (GROC) of the Royal Netherlands Academy of Sciences.

N.D. Haasbroek

Krayenhoff's triangulation in a part of Belgium, The Netherlands ( with the exception of the province of Limburg ), and a part of northwestern Germany, carried out between 1802 and 1811 and published in his Precis Historique was praised to the skies shortly after...

N.D. Haasbroek

In the past few years several papers in the Dutch language have been published on the triangulation of the Dutchman Snellius (Willebrord Snel van Royen, 1580 - 1626). It seems to be justified to bring these papers in a somewhat different form and in...

Report on the results of the measurements performed by T.J. Kukkamäki and T. Honkasalo of the Finnish Geodetic Institute

G.J. Bruins (Editor)

In 1913 the primary triangulation network of the Netherlands was augmented with a base line. This base line was measured near Stroe and the results of the measurements were published by Prof. Ir. Hk.J. Heuvelink in 1931.*)

Complete results with isostatic reduction

G.J. Bruins (Editor)

After the second World War, the Netherlands Geodetic Commission again took up the organization of gravity measurements at sea. The method of measurement and the apparatus which were developed and used during the years 1923 - 1938 by Prof.Dr. F.A. Vening Meinesz, resulted during that period in...

N.D. Haasbroek

As far as I know little has been published in literature concerning land surveying about the accuracy of plotting and scaling-off with divider and plotting scale or with tracing point and engineer scale. Only a rather circumstantial paper by...

Complete results with isostatic reduction, interpretation on the results

F.A. Vening-Meinesz

This publication contains a list of the complete results of the gravity expeditions at sea of the Netherlands Geodetic Commission up to the year 1938, i.e. of 844 stations, isostatically reduced according to the Hayford-Bowie reduction and to the Airy reduction for local compensation and for five degrees of regionality of the compensation, for crustal thicknesses T of 20 km and of 30 km.

J.E. de Vos van Steenwijk

The Netherlands Geodetic Commission publishes here a study made during the war by Dr. J. E. baron de Vos van Steenwijk about the shape of the geoid and the plumbline deflections in East Indonesia as derived from the gravity data in this area. For the first time the formulas expressing these relations have been applied here in...

F.A. Vening-Meinesz

The purpose of this publication is to give tables for the gravity effect of the isostatic compensation according to the Airy hypothesis of a floating crust and assuming a regional distribution of the compensating masses. For making the tables more complete and in order to allow a better comparizon, a first column has been added to the tables corresponding to local compensation. The figures of these last mentioned columns are identical to those of...

F.A. Vening-Meinesz

Chapter I contains the theoretical investigations about the effect of the accelerations of the pendulum apparatus on the gravity results. § I treats of the effect of the horizontal component perpendicular to the swinging plane of the main pendulums, § 2 of that of the second horizontal component, § 3 of that of the vertical component and § 4 of the rotational effects. In all cases the effect has been determined up to the terms proportional to...

F.A. Vening-Meinesz

This publication contains a report of the gravity at sea expeditions of the Netherlands Geodetic Commission in the years 1934 to 1939. It gives an account of the expeditions, the observations, the computation of the results and of their mean errors; the last table lists the gravity reduced to...

F.A. Vening-Meinesz, J.H.F. Umbgrove and Ph.H. Kuenen

The interpretation of gravity anomalies is a subject about which the opinions are yet divided. This results from its many-sided character. The problem has no unique mathematical solution and so only the combination of the gravity data with data from...

F.A. Vening-Meinesz

This volume contains the report of the maritime gravity expeditions of the Netherlands Geodetic Commission during the years 1923-1930. The results are reduced to sea-level without further reduction; they are put together in the list on pages 101 et seq. A second volume will contain the isostatic reductions of the results and the discussion of their interpretation.

F.A. Vening-Meinesz

To facilitate the use of this publication, a short summary will be given of the contents.

The first chapter contains the theory of the method for determining gravity at sea by means of pendulum observations. The results of these theoretical considerations, i.e. the formulae for the corrections and reductions which have to be applied to the observed pendulum-period, are put together in § 8. § 9 indicates the principal arrangement of...
